Parallelepiped package

ABSTRACT

A parallelepiped package for wafer-shaped articles comprising a blank of wrapping material wrapped hoselike around the content of the package and having its ends folded against opposite end walls of the content. A tape is wrapped around the package and provided at least at one portion covering the folded flaps of the wrapping with a perforated tear line. The tape is adhesively secured near its tearable portion to the wrapping material, so that the package may be opened at one end only without unwrapping the entire content of the same.

PATENTED JUN nan PARALLELEPIPED PACKAGE The invention'relates to aparallelepiped package for wafershaped articles and comprises a blank ofwrapping. material which after being placed in the form of a hose aroundthe content of the package is provided with a longitudinal fold, whilethe two ends of the hose are folded over the entire width of thepackage. in the fonn of transverse flaps which are inwardly folded insuch a manner that the transverse flaps are disposed in the plane of thelower and upper wall faces in which position these flaps are held by anendless tape which is wrapped around the entire package.

Packages of this type are already known. They have the property thatafter completely tearing off of the tape, both folded closures at theends of the package will be opened at the same time, in fact thewrapping material is completely open and exposes the entire'content ofthe package. This property of the package has, however, a disadvantage,particularly when it is desired to remove from the package only aportion of the content and one desires to close the package again. Thisis particularly the case when the package is used for stacks of crackersor wafer-shaped biscuits.

It is an object of the invention to improve a package of this type insuch a manner that it may also be used for the purpose of removing onlya portion of its content and then close it again. According to theinvention the tape which surrounds the package is provided at least atone place where it covers a transverse flap with a perforation, while atleast at one point of the larger sidewalls of the wrapping material, thetape is glued,

cemented or sealed thereto by a hot sealing operation.

The mentioned perforation makes it easy to tear the tape at the mostsuitable point of the package, while the gluing, cementing or sealing ofthe tape to the larger sidewalls of the package prevents a completeremoval of the tape from the package, so that the folded closure at theopposite side of the package remains closed.

The drawing illustrates an embodiment of the package of the invention.

In the drawing;

FIG. 1 illustrates a perspective view of a partially completed package,7

FIG. 2 is a perspective view of the completed package, and

FIG. 3 is a perspective view of the completed package, but having one ofits sides opened.

FIG. 1 which illustrates a partly completed package, for instance forcrackers, the wrapping material of which, for instance a blank of waxpaper, is wrapped like a hose around the content of the package in sucha manner that a longitudinal fold l is formed along one of the largesidewalls 5 of the package. The hose-shaped wrapper extends with its twoends beyond the content of the package and these ends are folded againstthe small sidewalls 2 by forming triangular folds 3 and outwardlyextending transverse flaps 4i.

For completing the package the two outwardly extending transverse flaps4 are folded into the plane of the small sidewalls 2 and then a tape 6is wrapped around the package in such a manner that the large sidewallsS and the small sidewalls 2 are covered, as this is shown in FIG. 2. Inorder to open this package the tape 6 has to be torn asunder.

In order to make the opening of the package easy, the tape 6 is providedat the place of the small sidewalls 2 which cover also the transverseflaps 4 with a line of perforations 7.- In order to prevent that thetape 6 after tearing along the perforation will be completely removedfrom the package and thereby would also-expose the transverse flaps 4 atthe other side of the package, .the tape 6 is secured by adhesive spots8 adjacent the edges 9 of the package with the larger sidewall 5 of thewrapping material.

FIG. 3 shows that only one end of the package has been opened while theopposite end of the package which also has a folded closure remainsclosed. If desired, the tape 6 by a suitable selection of the wrappingmaterial and tape material may be fixedly attached to the largersidewalls, for instance by means of a hot sealing operation.

What I claim is:

1. Parallelepiped package for wafer-shaped articles, comprising a blankof wrapping material which is wrapped hoselike around the content of thepackage and provided with a longitudinal fold extending along one of thelarger walls of said package, the ends of said hoselike wrapper beingclosed by folding said ends against opposite smaller walls of thecontent of the package and by forming at said smaller walls of thecontent of the package and by forming at said smaller walls transverseflaps folded against said smaller walls, and endless tape extendingaround said package and extending over said large: walls and said foldedflaps, the portion of said tape covering at least one of said foldedflaps being provided with a perforation permitting tearing of said tape,and means adhesively connecting said tape to said wrapping material atselected places of said larger sidewalls.

2. Package according to claim I, in which a perforated line extendsacross the entire width of said tape.

3. Package according to claim 1, in which said tape is adhesivelyconnected to said wrapping material adjacent the edges of said largerwalls.
